For those who use the ashtray in front as a coin box and use the lighter socket to plug in your phone charger. Just make sure that the coins do not fall into the lighter socket. This will blow the fuse, no big deal, but to replace the fuse is a pain. You need to go to the boot, remove the floor board, the fuse box and fuse diagram is there. You need the fuse diagram to figure out which fuse goes to supplies the socket. It is really stupid, does not show clearly what is what, they use diagrams instead of words like in the old days. Then you need to go to the engine compartment, there is another fuse box there, remove a cowling on the rear left hand side, check each fuse to see which one is blown, and discover that there are no spare fuses provided in this box. Or go to the service center to replace it.Either way it is a pain.BMW engineers, sigh.....
